(b)(4).Additional information: additional information was requested and the following was obtained: what is the patients status? unknown.Will further testing be carried out to determine if there is a leak? surgery (b)(6).Has the patient and does the patient continue to follow a correct dietary regimen? unknown.Can you please provide details of the fill history? following up with customer.What is the current amount of the fill in the band? unknown.Is the surgery scheduled for band removal? (b)(6).Will the band be returned for analysis? yes.(b)(6).What is the hospital name and address? (b)(6).Can you please provide the lot number? unknown.Will check.The port was returned with locking connector attached and 9cm of catheter detached.The lot number engraved on the port is zlkbdz.1.4cm of catheter remained on the tubing connection attached with the locking connector.The hooks were in closed position.Biological debris was evident around the port.Upon microscopic evaluation 22 punctures were visible on the septum.For the leak testing, the returned catheter was reattached to the port and tested.No leaks were observed on the catheter or the port.The returned components of the device (port and partial catheter) appear to be fully functional.No definitive conclusion can be drawn as the band/balloon of the device involved in this complaint has not been returned.Product analysis (visual and functional) does not confirm the event description, the partially returned device was found to be functioning.A device history record (dhr) review was carried out and no discrepancies were recorded on file in relation to the event.The product's instructions for use were reviewed with respect to balloon leakage and it was noted to caution against inadvertent perforation of the band from sharp instrumentation during implant.It was also noted that fluid loss from the balloon can occur at any time, for a number of reasons, including general deterioration of the balloon over time.A review of the manufacturing process was performed, and it was noted that the device is 100% leak tested before release.Therefore it is unlikely that the manufacturing process caused this event.
